Abstract

The utility model relates to an oil pumping well polish rod loading sensor mounting structure, wherein the housing of a sensor is provided with a U-shaped opening, one end of a stop lever is hinged with one portion located at one side of the U-shaped opening on the housing, a second portion located at the other side of the U-shaped opening on the housing is provided with a gap matched with the stop lever, a third portion located above the gap, of the housing is provided with a through hole with a step, inside the through hole there is provided a latch, the lower portion of the latch is provided with stop shoulders, the latch is sleeved by a spring, both ends of the spring respectively abuts against the step and the stop shoulders, and the stop lever is provided with a hole matched with the latch. When the stop lever is in an open state, the polish rod is in the U-shaped opening, the latch is raised up, the moving end of the stop lever is pushed into the gap of the housing, then the latch is released, and the latch extends into the hole on the stop lever under the action of the spring, thereby finishing mounting the sensor. Conversely, when the sensor is needed to be dismounted, the latch is raised up to quit from the hole on the stop lever, and the moving end of the stop lever is allowed to quit from the gap of the housing, thereby dismounting the sensor.

Description

Rod-pumped well PRL sensor fixing structure

Technical field

The utility model relates to the sensor that is used to measure the rod-pumped well PRL, specifically a kind of mounting structure of measuring the sensor of rod-pumped well PRL.

Background technology

In the rod-pumped well oil producing operation, need monitor in real time the load-position diagram of rod-pumped well.One of significant data of load-position diagram collection is exactly the load data of rod-pumped well polished rod.Existing rod-pumped well PRL sensor fixing structure has following two kinds: 1, load transducer is made tubular structure, is enclosed within during use on the polished rod of oil pumper; 2, housing one side of load transducer has U type opening, during use, polished rod is in the U type opening, pass bolt and cooperate in open side with nut, with sensor sleeve on the rod-pumped well polished rod.There is following deficiency respectively in the mounting structure of above-mentioned two kinds of sensors: 1, for the former; Must be in the installation process to side's card of polished rod top is laid down; After placing sensor also must with above Fang Kafang retighten, the whole erection process wastes time and energy, if the side fasten not in place; Also possibly cause polished rod to come off, cause the well site accident; 2, for the latter, need during installation earlier bolt, nut are pulled down, install sensor after, again bolt, nut are loaded onto, install loaded down with trivial details relatively.

The utility model content

The purpose of the utility model is to provide a kind of rod-pumped well PRL sensor fixing structure, this mounting structure can realize sensor fast, dismounting easily.

For realizing above-mentioned purpose; The utility model adopts following scheme: rod-pumped well PRL sensor fixing structure, have the U-shaped opening on the housing of sensor, and an end of a lever is hinged on housing and is positioned on the position of U-shaped opening one side; Housing is positioned on the position of U-shaped opening opposite side and has the breach that cooperates with lever; The position that housing is positioned at the breach top has the through hole with step, and latch is housed in the through hole, and the bottom of latch has shoulder block; The two ends of the spring that is with on the latch respectively with step and shoulder block against, have the hole that cooperates with latch on the lever.

Visible by such scheme, when the sensor with mounting structure that the utility model provides is installed on polished rod, under the state that lever is opened; Polished rod is in the U type opening, latch is upwards risen, the movable end with lever is pushed in the breach on the housing then; Unclamp latch subsequently; Under the effect of spring, latch extend in the hole on the lever, can accomplish the installation of sensor.Otherwise, in the time of need pulling down sensor, again latch is upwards risen, make its hole from lever and withdraw from, withdraw from the breach of movable end from housing with lever again, can pull down sensor.

The utility model is simple in structure, use is reliable, and it has easy for installation, characteristics efficiently.

Description of drawings

Fig. 1 is the structural drawing of the utility model one embodiment;

Fig. 2 is the A-A cut-open view of Fig. 1.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2

Have U-shaped opening 1a on the housing 1 of sensor, an end of a lever 2 is hinged on housing 1 and is positioned on the position of U-shaped opening 1a one side, and housing 1 is positioned on the position of U-shaped opening 1a opposite side and has the breach 1e that cooperates with lever 2.The position that housing 1 is positioned at breach 1e top has the through hole 1c with step 1d; Latch 3 is housed among the through hole 1c; The bottom of latch 3 has shoulder block 3a, the two ends of the spring 6 that is with on the latch 3 respectively with step 1d and shoulder block 3a against, have the hole 2b that cooperates with latch on the lever 2.The upper end of latch 3 is connected with a stop collar 4 through screw 5, and housing 1 upside has the gap 1b that can hold stop collar 4.

In addition, visible by Fig. 1, when surrounding polished rod, fit the face of cylinder 2a of middle parts that lever 2 is inboard preferably for caving in it for making lever 2.

Visible in conjunction with Fig. 1, Fig. 2, upwards push stop collar, it is upwards risen together with latch, when upwards pushing stop collar 5, can use flat mouthful screwdriver, the front end of screwdriver is inserted into the below of stop collar 5, can upwards lever up stop collar 5.
